Question

我使用以下代码片段来创建alertdialog。

AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, android.R.style.Theme_Holo_Light));
    View pickerView = getLayoutInflater().inflate(R.layout.picker_dialog, null);
    builder.setView(pickerView);
    builder.setMessage("AlertDialog").setCancelable(false).setPositiveButton("OK", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(getApplicationContext(), "got it!", Toast.LENGTH_SHORT).show();
        }
    }).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.cancel();
        }
    }).setNeutralButton("Neutral", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(getApplicationContext(), "neutralize", Toast.LENGTH_SHORT).show();
        }
    });

    AlertDialog alert = builder.create();
    alert.setTitle("number picker");
    alert.show();

问题是，当我使用此代码创建对话框时，这三个按钮没有均匀放置，如下所示：

实际上我想得到的是这样的：

其中两个按钮的位置相同

我知道这是alertdialog主题的问题。但我尝试了无数次，我无法改变任何事情。

有人可以告诉我如何处理主题以获得像第二个一样的警告对话吗？

picker_dialog的布局文件如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">

<EditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="input"/>

</LinearLayout>

我遵循Android - Make AlertDIalog buttons a uniform size的建议。代码如下：

AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, android.R.style.Theme_Dialog));
    View pickerView = getLayoutInflater().inflate(R.layout.picker_dialog, null);
    builder.setView(pickerView);
    builder.setMessage("AlertDialog").setCancelable(false).setPositiveButton("Verify", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(getApplicationContext(), "got it!", Toast.LENGTH_SHORT).show();
        }
    });
    builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.cancel();
        }
    });
    builder.setNeutralButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(getApplicationContext(), "Neutral", Toast.LENGTH_SHORT).show();
        }
    });

    final AlertDialog alert = builder.create();
    alert.setTitle("number picker");
    alert.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dialog) {
            Button posButton = alert.getButton(DialogInterface.BUTTON_POSITIVE);
            Button negButton = alert.getButton(DialogInterface.BUTTON_NEGATIVE);
            Button neuButton = alert.getButton(DialogInterface.BUTTON_NEUTRAL);

            LinearLayout.LayoutParams posParams = (LinearLayout.LayoutParams) posButton.getLayoutParams();
            posParams.weight = 1;
            posParams.width = LinearLayout.LayoutParams.MATCH_PARENT;
            posParams.height = LinearLayout.LayoutParams.WRAP_CONTENT;

            LinearLayout.LayoutParams negParams = (LinearLayout.LayoutParams) negButton.getLayoutParams();
            negParams.weight = 1;
            negParams.width = LinearLayout.LayoutParams.MATCH_PARENT;
            posParams.height = LinearLayout.LayoutParams.WRAP_CONTENT;
            LinearLayout.LayoutParams neuParams = (LinearLayout.LayoutParams) neuButton.getLayoutParams();
            neuParams.weight = 1;
            neuParams.width = LinearLayout.LayoutParams.MATCH_PARENT;
            neuParams.height = LinearLayout.LayoutParams.WRAP_CONTENT;


            posButton.setLayoutParams(posParams);
            negButton.setLayoutParams(negParams);
            neuButton.setLayoutParams(neuParams);
        }
    });
    alert.show();

以上是完成以下链接建议后的代码。我只得到了这个：

似乎正面按钮已经推到右上角并消失了。

有人可以解决这个问题吗？

根据Kushan的建议，我从showshow listener的对话框中取出布局设置代码，完整代码如下：

AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, android.R.style.Theme_Dialog));
    View pickerView = getLayoutInflater().inflate(R.layout.picker_dialog, null);
    builder.setView(pickerView);
    builder.setMessage("AlertDialog").setCancelable(false).setPositiveButton("Positive", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(getApplicationContext(), "got it!", Toast.LENGTH_SHORT).show();
        }
    });
    builder.setNegativeButton("Negative", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.cancel();
        }
    });
    builder.setNeutralButton("Neutral", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(getApplicationContext(), "Neutral", Toast.LENGTH_SHORT).show();
        }
    });

    AlertDialog alert = builder.create();
    alert.setTitle("number picker");
    alert.show();

    LinearLayout.LayoutParams buttonParams;
    Button buttonPositive = alert.getButton(AlertDialog.BUTTON_POSITIVE);
    buttonParams = (LinearLayout.LayoutParams) buttonPositive.getLayoutParams();
    buttonParams.weight = 1;
    buttonParams.width = buttonParams.MATCH_PARENT;

    Button buttonNegative = alert.getButton(AlertDialog.BUTTON_NEGATIVE);
    buttonParams = (LinearLayout.LayoutParams) buttonNegative.getLayoutParams();
    buttonParams.weight = 1;
    buttonParams.width = buttonParams.MATCH_PARENT;

    Button buttonNeutral = alert.getButton(AlertDialog.BUTTON_NEUTRAL);
    buttonParams = (LinearLayout.LayoutParams) buttonNeutral.getLayoutParams();
    buttonParams.weight = 1;
    buttonParams.width = buttonParams.MATCH_PARENT;

我得到了与上面相同的结果

尝试提醒您如下所示的对话框代码：

 AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, android.R.style.Theme_Holo_Light));
View pickerView = getLayoutInflater().inflate(R.layout.picker_dialog, null);
builder.setView(pickerView);
builder.setMessage("AlertDialog").setCancelable(false).setPositiveButton("OK", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        Toast.makeText(getApplicationContext(), "got it!", Toast.LENGTH_SHORT).show();
    }
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        dialog.cancel();
    }
}).setNeutralButton("Neutral", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        Toast.makeText(getApplicationContext(), "neutralize", Toast.LENGTH_SHORT).show();
    }
});

AlertDialog alert = builder.create();
alert.setOnShowListener(new DialogInterface.OnShowListener() {
    @Override
    public void onShow(DialogInterface dialog) {
        Button negativeButton = ((AlertDialog) dialog).getButton(DialogInterface.BUTTON_NEGATIVE);
        Button positiveButton = ((AlertDialog) dialog).getButton(DialogInterface.BUTTON_POSITIVE);
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, 2f);
        negativeButton.setLayoutParams(params);
        positiveButton.setLayoutParams(params);

        negativeButton.invalidate();
        positiveButton.invalidate();
    }
});
alert.setTitle("number picker");
alert.show();

Answer 2

更改对话框的主题。

它将解决您的问题。

使用xml布局中的Holo.Dialog并从预览中进行检查。

如果您想要这样的按钮，则必须使用weightSum。

希望这有用。

嗨，您可以使用自己的自定义布局来制作自定义对话框她是一个示例代码

 private void CustomAlert ()
{

        final Dialog dialog = new Dialog(this);
        dialog.setContentView(R.layout.CustomViewName );
        dialog.setTitle(R.string.Upload_File_now);
        dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

        final EditText description_editTextField = (EditText) dialog.findViewById(R.id.descriptionEditText);
        final EditText locationEditText = (EditText) dialog.findViewById(R.id.placeEditText);

        Button cancel_btn = (Button) dialog.findViewById(R.id.cancel_btn);
        cancel_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                dialog.cancel();
            }
        });

        Button send_btn = (Button) dialog.findViewById(R.id.send_btn);
        send_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                String location = locationEditText.getText().toString().trim();
                String description = description_editTextField.getText().toString().trim();
                boolean isUrgent = ((CheckBox)dialog.findViewById(R.id.checkBoxUrgent)).isChecked();

                dialog.cancel();
            }
        });
        dialog.show();
    }

我希望这可以帮助您完成项目

您好您可以像这样使用CustomDialog

在XML

中

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<ImageView
    android:id="@+id/image"
    android:layout_width="50dp"
    android:layout_height="50dp"
    android:contentDescription="@drawable/ic_launcher"
    android:src="@drawable/ic_launcher" />

<Button
    android:id="@+id/button"
    android:layout_width="100dp"
    android:layout_height="wrap_content"
    android:layout_below="@+id/image"
    android:layout_centerHorizontal="true"
    android:text="Dismiss" />

<TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:layout_above="@+id/button"
    android:layout_toRightOf="@+id/image"
    android:gravity="center_vertical"
    android:textAppearance="?android:attr/textAppearanceMedium" />

</RelativeLayout>

In Avtivity

final Dialog dialog = new Dialog(MainActivity.this);

        //setting custom layout to dialog
        dialog.setContentView(R.layout.cusotm_dialog_layout);
        dialog.setTitle("Custom Dialog");

        //adding text dynamically
        TextView txt = (TextView) dialog.findViewById(R.id.textView);
        txt.setText("Put your dialog text here.");

        ImageView image = (ImageView)dialog.findViewById(R.id.image);
        image.setImageDrawable(getResources().getDrawable(android.R.drawable.ic_dialog_info));

        //adding button click event
        Button dismissButton = (Button) dialog.findViewById(R.id.button);
        dismissButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });
        dialog.show();
